AWR1443BOOST: Level Sensing - High Accuracy Demo

Jerry Leung
Prodigy 10 points
Part Number: AWR1443BOOST
Other Parts Discussed in Thread: UNIFLASH, , AWR6843AOPEVM

Hello,

I purchasesd an AWR1443BOOST and I am trying to use the High Accuracy Demo to get an understanding of the Zoom-FFT technique to achieve mm range accuracy.  I flashed the evm with the prebuild binaries using uniflash and it seemed to be successful. 

However, when I tried running it in the High Accuracy Visualizer and loading the high_accuracy_demo_14xx.cfg it seems to be running into an issue with the config file.  

So want to see if there's something I'm missing or perhaps need to update the config file somehow? Thanks for any pointers.

Best.

Jerry

    Hi Jerry, 

    Can you please let me know which version of the Radar Toolbox that you have obtained this demo from. Please also let me know if you have made any modifications in the configuration file for the demo or you are using it completely unmodified.

    Best Regards,

    Josh

    I am currently using the radar_tool_box_1_20_00_11 and I have not made any changes to the cfg file.

    I also tried it with an older tool box radar_tool_box_1_00_00_26 but also running into the same issue.

    And just making sure it's not the board or the setup, I re-flashed the out of box demo and it seems to be working.

    Hi Jerry, 

    Thank you for this information. I have just tested this on my end with Radar Toolbox 1.20 and it is working so I may need a bit more information to help you identify the issue. Seeing as the Out-of-Box demo is running just fine I don't expect a hardware issue.

    Based on your previous replies I believe you are using the correct files but please confirm that the following files are being used. 

    1. Board is flashed with <RADAR_TOOLBOX_INSTALL_DIR>\source\ti\examples\Level_Sensing\high_accuracy\prebuilt_binaries\xwr14xx_high_accuracy_mss.bin
    2. <RADAR_TOOLBOX_INSTALL_DIR>\source\ti\examples\Level_Sensing\high_accuracy\chirp_configs\high_accuracy_demo_14xx.cfg
    3. Visualizer used at this link: https://dev.ti.com/gallery/view/6813269/High_Accuracy_Visualizer/ver/2.0.1/

    Also the User Guide for this demo specifies that Google Chrome browser should be used. Are you using Google Chrome?

    Best Regards,

    Josh

    Hi Josh,

    Yes that all seems to be correct from what you wrote. To doubled check I downloaded a fresh installation of the radar tool box here. 

    I placed a jumper on SOP2 and flashed the corresponding binary following the directory, shown in the gif below:

    Upon successful flash, I exited out of UniFlash, removed jumper SOP2, and pressed on the NRST button, and opened up the High Accuracy Visualizer.  There I connected the eval board and tried loading the config file.

    One thing I'm not sure if it's actually an issue but I noticed that it seems to be stuck trying to connect to the 2nd target.  Although I'm not sure if that's related to the error message I'm getting regarding the cfg file. 

    Lastly just to note, I purchased the eval board off digikey, not sure if there's any hardware differences.  On UniFlash it recognizes it a RevB

    Forgot to explicitly note but I am using Google Chrome.  Thanks for the help in advance!

    Hi Jerry, 

    I'm very sorry for the delayed response here. Unfortunately I still have been unsuccessful in reproducing this issue. Can you please let me know the Silicon PG Revision for your device? You can identify the version by comparing the markings on the IC to the diagram in the 'Device Nomenclature' section of the datasheet:https://www.ti.com/lit/ds/symlink/awr1443.pdf 

    Also thank you for sharing the gifs of the procedure that you are following. I can confirm the procedure is correct and the files used are correct assuming they have not been modified. The message 'connecting to 1 of 2 targets' is expected and not the issue here. 

    Another thing you can try would be to run this demo using a serial terminal emulator (TeraTerm, etc...) rather than the visualizer. This will allow us to confirm whether the issue is occurring in the visualizer or on the device itself. 

    Best Regards,

    Josh

    Hi Josh,

    Looks like it's the production version without any prefix. 

     

    I connected it with putty and entered each command from the chirp cfg file.  It looks like it's fine up until I try sensorStart, then it throws an Error -1.

    Quick check, should the header have any indication that it should be the high accuracy demo?

    Hi Jerry, 

    Based on the markings on the IC it seems your device is Silicon PG Revision 1.0. This is likely the cause of the issue that you are facing. The demo you are trying to run is built with SDK 2.1.x which only supports xWR1443 PG Revision 3.0. 

    You might have some luck with trying an older version of the demo which has been deprecated. Please note, we will be able to offer very little to no support on these forums for deprecated content. If you do want to try this route, then you should be able to use the High Accuracy demo in the Industrial Toolbox 3.2. To get Industrial Toolbox 3.2 (Or any older version of the toolbox) follow these steps:

    1. Select Manage Versions
    2. Select Summary


    3. Find Industrial Toolbox (or Automotive Toolbox) and select the arrow. 


    4. Select the version you want to show. 

    Otherwise I would recommend getting an EVM directly from TI.com which will ship with the latest silicon version. And should run with the latest software without any issues.

    Best Regards,

    Josh

    Thanks Josh for looking into this and pointing me to the right direction. I purchased the AWR6843AOPEVM and was able to successfully run the high accuracy demo. 

    I did try downloading the older industrial toolbox but ended up running into some issues when trying to flash it with Uniflash.  But I understand that it's deprecated content so I think we can just move on from here. 

    Thanks and appreciate the help.
